What version is your kafka cluster and what version consumers are you using? Do you know if your consumer group offsets are stored within Kafka, or within a zookeeper instance?
KafkaWebView currently only supports viewing consumer groups which store their state within Kafka. My guess is your consumers are storing their state in Zookeeper instead, are you able to confirm this?
If not, it's possible something else is going on.
Thanks

Hi @Crim
I am using Kafka cluster version 0.10.0.1 and I am using spring-kafka integration v1.2.1 which has the same version on the consumer. I believe now I am seeing the consumer group (CG.PMTS.CARD.EVENTS) in the list on the view page, however upon clicking on the link I am seeing the below error and the section Consumer CG.PMTS.CARD.EVENTS Positions
is not loading. I am seeing a topic exists named as __consumer_offsets
which stores the offsets in Kafka seems. Is the below error related to any versioning issue on the KafkaWebView and the connecting Kafka cluster?
Error org.apache.kafka.common.errors.UnsupportedVersionException: The broker only supports OffsetFetchRequest v1, but we need v2 or newer to request all topic partitions. (show more)

Sorry for the super delayed response. I believe that feature is not supported on brokers older than 0.11.0.x
